Constantinople II

Emperor Justinian I
About 165 bishops
Outcome
What the council decided
Condemned the Three Chapters and clarified the interpretation of Chalcedon in an anti-Nestorian direction.
Why it matters
The doctrine at stake
This council matters because it shows how councils are received and interpreted, not merely announced.
Council teaching
Interpreting Chalcedon through Ephesus
The council insisted that the confession of two natures must never be used to divide Christ into two persons or two sons.
It defended the continuity between Ephesus and Chalcedon by reading Chalcedon in a Cyrilline, anti-Nestorian direction.
Controversy explained
The Three Chapters controversy
The Three Chapters involved writings and figures suspected of preserving Nestorian tendencies. Condemning them was meant to reassure those who feared Chalcedon had weakened Ephesus.
The controversy also showed how imperial politics, regional mistrust, and theological precision could become entangled.

Received as the fifth ecumenical council, though its reception in parts of the West was difficult at first.
Orthodox
Received as ecumenical and important for an anti-Nestorian reading of Chalcedon.
Protestant
Usually treated as part of the classical conciliar inheritance, though less emphasized than the first four councils.
Oriental Orthodox
Not received as ecumenical, since it belongs to the post-Chalcedonian council sequence.
